This PCI-E SR-IOV virtual function (VF) driver is dependant upon the
physical function (PF) driver (i40e) for nearly all of its hardware
configuration. Requests from the VF driver are passed to the PF using
the hardware's Admin Queue.
This patch contains the functionality for communicating with the PF
driver. Because of the delay inherent in this communications channel,
most of the replies from the PF driver are handled asynchronously. The
exceptions are the "send API version" and "get VF config" messages,
which busy-wait because they are done so early during init that
interrupts are not yet configured.

Even with the quirks in commit dabdaf0c (mcs7830: Fix link state
detection) there are still spurious link-down events for some chips
where the false link-down events count go over a few hundreds.
This patch takes a more conservative approach and only looks at
link-down events where the link-down state is not combined with other
states (e.g. half/full speed, pending frames in SRAM or TX status
information valid). In all other cases we assume the link is up.
Tested on MCS7830CV-DA (USB ID 9710:7830).

====================
slight optimization of addr compare for net modules
This is the second patchset for slight optimization of address compare,
mainly for net tree, just following the Joe's opinion, it will help review
the code for maintainers and supports.
v2: Change some style for patch 2.
According Eric's suggestion, use the ether_addr_equal_64bits to instead
of ether_addr_equal for patch 19.
In fact, there are a lot of places which could use ether_addr_equal_64bits
to instead of ether_addr_equal, but not this time, thanks for Joe's
opinion.
v3: Change some style for patch 11/19:
(net: packetengines: slight optimization of addr compare).
Joe pointed out that is_broadcast_ether_addr(addr) would be appropriate here,
but this should be left alone and not in this patch, so fix it later.
In the patch (net: caif: slight optimization of addr compare), the operand for
memcmp is not mac address, so it is unsuitable to use the ether_addr_equal
to compare a non mac address, so remove the patch from the series.

When the vlan code detects that the real device can do TX VLAN offloads
in hardware, it tries to arrange for the real device's header_ops to
be invoked directly.
But it does so illegally, by simply hooking the real device's
header_ops up to the VLAN device.
This doesn't work because we will end up invoking a set of header_ops
routines which expect a device type which matches the real device, but
will see a VLAN device instead.
Fix this by providing a pass-thru set of header_ops which will arrange
to pass the proper real device instead.
To facilitate this add a dev_rebuild_header(). There are
implementations which provide a ->cache and ->create but not a
->rebuild (f.e. PLIP). So we need a helper function just like
dev_hard_header() to avoid crashes.
Use this helper in the one existing place where the
header_ops->rebuild was being invoked, the neighbour code.
With lots of help from Florian Westphal.

In order to facilitate development for netlink protocol dissector,
fill the unused field skb->pkt_type of the cloned skb with a hint
of the address space of the new owner (receiver) socket in the
notion of "to kernel" resp. "to user".
At the time we invoke __netlink_deliver_tap_skb(), we already have
set the new skb owner via netlink_skb_set_owner_r(), so we can use
that for netlink_is_kernel() probing.
In normal PF_PACKET network traffic, this field denotes if the
packet is destined for us (PACKET_HOST), if it's broadcast
(PACKET_BROADCAST), etc.
As we only have 3 bit reserved, we can use the value (= 6) of
PACKET_FASTROUTE as it's _not used_ anywhere in the whole kernel
and not supported anywhere, and packets of such type were never
exposed to user space, so there are no overlapping users of such
kind. Thus, as wished, that seems the only way to make both
PACKET_* values non-overlapping and therefore device agnostic.
By using those two flags for netlink skbs on nlmon devices, they
can be made available and picked up via sll_pkttype (previously
unused in netlink context) in struct sockaddr_ll. We now have
these two directions:
- PACKET_USER (= 6) -> to user space
- PACKET_KERNEL (= 7) -> to kernel space
Partial `ip a` example strace for sa_family=AF_NETLINK with
detected nl msg direction:
syscall: direction:
sendto(3, ...) = 40 /* to kernel */
recvmsg(3, ...) = 3404 /* to user */
recvmsg(3, ...) = 1120 /* to user */
recvmsg(3, ...) = 20 /* to user */
sendto(3, ...) = 40 /* to kernel */
recvmsg(3, ...) = 168 /* to user */
recvmsg(3, ...) = 144 /* to user */
recvmsg(3, ...) = 20 /* to user */

sctp: Consolidate and ratelimit deprecation warnings
The SCTP protocol has several deprecation warnings in its setsockopt path that
can be triggered by unprivlidged users. Since these are not ratelimited, we can
spam the logs quite easily here. Since these are all deprecation warnings, and
that type of warning isn't uncommon in the rest of the kernel, lets make a
common pr_warn_deprecated macro to produce somewhat generalized ratelimited
deprecation warnings easily

During a recent discussion regarding some sctp socket options, it was noted that
we have several points at which we issue log warnings that can be flooded at an
unbounded rate by any user. Fix this by converting all the pr_warns in the
sctp_setsockopt path to be pr_warn_ratelimited.
Note there are several debug level messages as well. I'm leaving those alone,
as, if you turn on pr_debug, you likely want lots of verbosity.
